Lead inspectors shall retain a copy of each lead inspection and lead determination report for a minimum of seven years at his or her principal place of business or at an archive facility approved in advance by the Department. Complete reports shall be made available to the Department upon request.Risk assessments. The objectives of a risk assessment are to identify and report on the existence, nature, severity, source, and location of lead-based paint hazards and lead hazards; and to identify and report on options for reducing or eliminating identified lead-based paint hazard or lead hazards, including interim controls or abatement measures, or both. A complete risk assessment is performed on the entire dwelling unit and all common areas; the scope of a targeted risk assessment is determined through contract. Complete and targeted risk assessments. Complete and targeted risk assessments include the following:Visual assessment. The risk assessor shall perform a visual assessment of the residential dwelling unit or child-occupied facility, exterior building surfaces and any surrounding land belonging to the owner to identify potential lead-based paint hazards or lead hazards, as follows:If prior lead inspection reports are available, risk assessors shall consider whether the past lead inspection conforms to current standards. If the prior lead inspection is determined to be reliable and complete, the risk assessor is only required to visually assess surfaces that have been determined to contain lead-based paint. If a lead inspection has not been completed or if the risk assessor determines that the lead inspection report is or may be unreliable, a complete lead inspection shall be conducted in accordance with the requirements of Section 7(A)(1). A targeted risk assessment shall include the testing of all painted surfaces in poor condition in accordance with the requirements of Section 7(A)(1) within the area of the residence contracted for risk assessment. The risk assessor may assume that inaccessible surfaces with paint in poor condition contain lead-based paint.The risk assessor shall identify potential soil and water hazards on the property. The risk assessor shall examine buildings and the work area for structural deficiencies, substrate deficiencies, and other conditions that contribute to observed paint deterioration and other potential lead-based paint hazards (i.e., lead paint dust, water, such as deterioration in the roof that results in water leaks).Evaluation of potential lead hazards. The risk assessor shall determine if the potential hazards identified during the visual assessment are lead-based paint hazards or lead hazards.Poor condition paint. Painted surfaces in poor condition with lead-based paint shall be considered lead-based paint hazards.Friction and impact surfaces. Friction and impact surfaces with lead-based paint may be identified as a lead-hazard dependent upon the surface condition. Friction surfaces that are subject to abrasion and where the lead dust level on the nearest horizontal surface is equal to or greater than the dust lead hazard identified in Section 7(B)(2)(c), or an impact surface with chipping or flaking lead-based paint caused by impact from an adjacent surface and where the lead dust level on the nearest horizontal surface is equal to or greater than the dust lead hazard identified in Section 7(B)(2)(c), may be lead hazards. Risk assessors may recommend that these surfaces be repaired to prevent the development of lead hazards.Dust. Dust tests of all selected residential dwelling unit and child-occupied facilities shall be performed in accordance with Section 7(C)(1) to determine if lead-contaminated dust is present. A lead-based paint hazard exists if the single surface results for any room equivalent are equal to or exceeds the following quantities of lead-contaminated dust:Hard floors, porches, and other horizontal surfaces - 10 ug/ft2.Carpeted floors - 10 ug/ft2.Interior windowsills and/or window troughs - 100 ug/ft2.Soil. If bare soil is identified during a visual assessment soil tests must be performed in accordance with Section 7(C)(2). If the test results are equal to or exceeds 100 ppm in bare soil play areas or 900 ppm from the perimeter of the building in other than play areas, the soil in these areas shall be considered a lead hazard.Water hazard assessment. Water shall be sampled in accordance with the requirements of Section 7(C)(3). If any of the test results equal to or exceed 15 ppb the water shall be considered a lead hazard.Survey. The risk assessor may survey the occupants to determine whether an occupant’s occupation or hobbies pose a risk that lead may be brought into the residence from those activities.Identify acceptable lead-based paint hazard and lead hazard control options. Using information on existing lead hazards and the condition of the building, the risk assessor shall identify acceptable lead-based paint hazard or lead hazard control methods. Control options include abatement and interim controls. Lead abatement activities shall be conducted in accordance with the work practice requirements contained in Section 6.Multiple units. When conducting risk assessments in multi family dwelling unit the risk assessor shall use Appendix D of this Chapter for determining the required number of units to be assessed and the required number of dust and soil samples to be collected.Risk assessment reports. The risk assessor shall prepare and provide to their client a report, which shall include the following information: Date of the risk assessment;Address of each building;Date of construction of buildings (approximate if unknown);Apartment number (if applicable);Name, address, and telephone number of each owner of each building or dwelling unit;Name, signature, and Maine certification number of the risk assessor conducting the risk assessment;Name, address, and telephone number of each laboratory conducting analysis of collected samples. Laboratories performing analyses must be accredited in accordance with the requirements of Section 7(D);An explanation of how to understand the risk assessment report;A summary by room of all components that contain lead-based paint, including the clear identification of all lead-based paint hazards and lead hazards;Testing method and sampling procedure for analyses employed;Identification of the existence, nature, severity, source, and location of all lead-based paint hazards and lead hazards;A description of structural and substrate condition for each identified lead-based paint hazard;Acceptable methods for control of all lead-based paint hazards and lead hazards identified, including interim controls and/or abatement methods;All data collected from on-site testing, including quality control data and the serial number of all XRF device(s) used to perform analyses;All results of laboratory analysis on collected paint, soil, dust, and water samples;A lead-safe certificate, if applicable;A brief description of a pre-1978 residential dwelling unit or child occupied facility, and line diagrams showing the rooms, including the common areas of a residential dwelling unit or child occupied unit should be included in the risk assessment; and Risk assessment reports including recommendations are valid for one year and can only be amended or changed by performing a new risk assessment.Lead hazard screen. A lead hazard screen is a limited risk assessment appropriate in dwelling unit in good condition where the probability of finding lead-based paint hazards is low. If dust levels for windowsills are equal to or exceed 50 ug/ft2 or if the dust level for a hard or carpeted floor is equal to or exceeds 5 ug/ft2, then a risk assessment is warranted. At a minimum, a lead hazard screen includes the following:Background information regarding the physical characteristics of the residential dwelling unit or child-occupied facility. Occupant use patterns that may cause lead-based paint exposure to children less than 6 years of age.A visual inspection to determine if any paint in poor condition is present and to locate at least two dust sampling locations.Testing for lead of each surface or testing combination with paint in poor condition.Two composite dust samples, one from the floors and others from the windowsills in rooms, hallways, or stairwells, including common areas, where any child less than 6 years of age is most likely to come in contact with lead paint dust.A lead hazard screen report including all information gained during the lead hazard screen, including: a narrative describing the background information, occupant use patterns, and the visual inspection; a description of any testing combinations used; the locations from which samples were collected, including an explanation of any composite sampling; and recommendations on the need for any follow-up inspection or risk assessment and interim controls and/or lead abatement to reduce lead-based paint hazards.(5) Summary reports to the Department. Within 30 of completion of each risk assessment and/or lead hazard screening, the risk assessor shall submit to the Department a summary report in a form approved by the Department.

The Department may also approve other sampling and analytical methods if the laboratory and the analytical method used by that laboratory to analyze the sample is NLLAP accredited and the laboratory has Maine certification for the analytical method.E.Lead-safe evaluationsA residential dwelling unit or child-occupied facility may be certified as lead-safe provided that a lead inspector or risk assessor has determined that no lead-based paint hazard or lead hazards exist. In order to determine that a residential dwelling unit or child-occupied facility is lead-safe, the lead inspection or risk assessment must include sampling and analysis of paint in accordance with the requirements of Section 7(A)(1), dust sampling in accordance with the requirements of Section 7(C)(1), soil sampling in accordance with the requirements of Section 7(C)(2) and water sampling in accordance with Section 7(C)(3). The lead inspector or risk assessor shall provide the owner a lead-safe certificate for each applicable residential dwelling unit or child-occupied facility. The lead-safe certificate shall at a minimum include the information contained in the body of the sample lead-safe certificate, included as Appendix B of this Chapter.Note:A lead inspector or risk assessor may issue a lead-safe certificate stating that soil sampling was not conducted due to an inability to identify whether bare soil is present because of snow cover or because the ground was frozen at the time of the inspection or risk assessment. Soil sampling shall be performed at the first six-month reevaluation if bare soil is present.Limited lead-safe certificate. A limited lead-safe paint and dust certificate may be issued when a lead inspector or risk assessor has determined that no lead-based paint, lead hazard or lead dust hazards exists within the residential or child-occupied facility. The limited certificate must state that soil and/or water sampling was not conducted during the inspection or risk assessment, and that the owner and residents should presume that any bare soil near the building perimeter of a pre-1978 structure is a potential lead hazard. The limited lead-safe certificate shall at a minimum include the information contained in the body of the sample lead-safe certificate, included as Appendix B of this Chapter.In order to maintain a lead-safe status the owner must pay for reevaluation of residential dwelling unit or child-occupied facility and must comply with the following requirements:For units that have been identified as having no lead-based paint hazards and not lead hazards which contain no lead-based paint, no reevaluation is necessary.For all other units, a lead inspector or risk assessor shall perform a reevaluation six months after the initial inspection or risk assessment date and annually thereafter, whenever occupancy changes if an essential maintenance practices plan is not implemented, and immediately after unexpected events which could cause deterioration of a lead-painted surface. Based on the results of three consecutive reevaluations evidencing that the owner is maintaining the residential unit and common areas as lead-safe, the lead inspector or risk assessor may decrease the frequency of reevaluations to once every two years. A reevaluation to determine lead-safe status paid for by the building owner, is a modified lead inspection or risk assessment consisting of a visual assessment of painted surfaces, limited dust, and if applicable soil and water sampling. It also includes the review of any renovation and remodeling, maintenance or abatement activities conducted since the issuance of the certificate and a review of an implemented Essential Maintenance Program set forth in Section 7(E)(7) below if applicable. To establish the lead-safe status of multi-family residential dwelling unit or child-occupied facilities containing greater than 5 units, the inspector or risk assessor shall use Appendix D of this Chapter for determining the required number of units to be assessed and the required number of dust and soil samples to be collected.Reevaluations shall identify:Changes in documented paint condition;Evidence of renovation, remodeling and maintenance activities;Evidence of failed lead abatement methods; and Lead-contaminated dust, soil or drinking water.Reevaluations shall be performed in accordance with the following requirements:A lead inspector or risk assessor shall perform a visual assessment to identify any deteriorated lead-based paint:The lead inspector or risk assessor shall review any past lead inspection report, risk assessment report, lead abatement reports, reevaluation reports and documentation related to renovation and maintenance activities and the essential maintenance program, as applicable.A visual assessment of all renovation and remodeling, maintenance, and abatement activities to determine whether the paint affected by these activities is still intact and a visual assessment of the unit to identify potential lead dust.A visual assessment of the exterior to identify any new lead-based paint hazards, areas of bare soil, and whether prior interim soil control or abatement measures are still effective.For paint surfaces in poor condition identified during the visual assessment for which reliable information about lead content is unavailable, the lead inspector or risk assessor shall measure the lead content by XRF or paint chip laboratory analysis performed in accordance with the requirements of Sections 7(A) and 7(D). If the owner, lead inspector or risk assessor assumes that inaccessible surfaces with paint in poor condition contain lead-based paint, analysis of the paint's lead content is not required. Upon completion of the visual assessment documenting that there is no lead-based paint in poor condition, the lead inspector or risk assessor shall begin dust sampling. Dust sampling of dwelling units and common areas shall be performed as follows:If the residential dwelling unit or child-occupied facility contains both carpeted and uncarpeted living areas, separate floor samples are required from the carpeted and uncarpeted areas.Dust samples shall be collected from locations selected in accordance with Section7(C)(1)(b) and (c).If a residential dwelling unit or child-occupied facility is found to contain lead levels that exceed the standards in Section 6(L)(1), that residential dwelling unit or child-occupied facility shall be cleaned by a sequence of HEPA vacuuming, wet cleaning, and HEPA vacuuming. The unit shall then be resampled to determine lead dust levels.Soil testing if applicable shall be performed as part of a reevaluation if new areas of bare soil are identified during the visual assessment. Soil samples shall be collected from locations selected in accordance with Section 7(C)(2).A lead-safe certificate under Section 7(E)(1) shall not be issued until a lead inspector or risk assessor documents that all paint surfaces are intact, dust samples meet the standards in Section 6(L)(1) and any new areas of bare soil do not contain lead above applicable thresholds and prior soil interim control or abatement measures are still effective. Reporting. Following reevaluation, the lead inspector or risk assessor shall prepare and provide to the client a written report documenting the presence or absence of lead-based paint hazards or lead hazards. The report shall:Describe any new lead-based paint hazards or lead hazards identified and summarize how they were mitigated either through minor maintenance, certified renovator, or lead abatement methods;Identify the date by which the next reevaluation must occur in order to maintain a lead-safe certificate, if applicable. If ownership of the property is transferred, a new reevaluation schedule must be initiated; andReview the Essential Maintenance Program and recommend changes as needed.Lead-safe certificate report. When all required reevaluations are completed and any new identified lead-based paint hazards or lead hazards successfully controlled or abated, the residential dwelling unit or child-occupied facility may be certified as lead-safe. The report may use information that remains valid from any previous lead inspections, risk assessments, or lead-safe evaluation on the residential dwelling unit or child-occupied facility. The lead inspector or risk assessor shall prepare and submit to the client a report with the following information whenever a residential dwelling unit or child-occupied facility is certified as lead-safe:Date of the lead-safe evaluation;Address of each building;Date of construction of buildings (approximate if unknown);Apartment number (if applicable);Name, address, and telephone number of each owner of each building;Name, signature, and Maine certification number of the lead inspector(s) or risk assessor(s) conducting the lead inspection or risk assessment;Testing method and sampling procedure for paint analysis that was employed;Specific locations of each painted testing combination tested for the presence of lead if tested;All data collected from on-site testing, including quality control data and the serial number of any XRF device(s) used to perform analyses;Name, address, and telephone number of each laboratory conducting analysis of collected samples. Laboratories performing analyses must be accredited in accordance with the requirements of Section 7(D);Any other sampling results;The identification of any components on which lead-based paint was previously detected that no longer have lead-based paint due to abatement activities, renovation and remodeling activities, or the implementation of essential maintenance practices; andA lead-safe certificate.Essential maintenance program. The essential maintenance program, if developed, shall be reviewed by the lead inspector or risk assessor as part of each reevaluation in order to certify that a residential dwelling unit or child-occupied facility is lead-safe. For all units with identified lead-based paint the following essential maintenance program components, as applicable, may be developed by a lead inspector or risk assessor. Develop and maintain a list of all suspected and known lead-based painted surfaces.Designate and provide lead awareness and work practice training to individuals who will be responsible for performing minor maintenance activities not subject to the EPA Lead-Based Paint, Renovation, Repair and Painting Rule, 40 C.F.R. Part 745, subpart E, as amended up to July 1, 2020.Classify the lead-based paint minor maintenance activities that may be performed as part of the essential maintenance program. Develop and implement an in-house review system to determine whether the maintenance activity is a minor maintenance activity or an activity that must be conducted by a certified renovator.Document each minor maintenance activity, including the location and action(s) performed.Document that all maintenance activities subject to the requirements of the RRP rule were performed by a certified renovator. Educate the resident(s) concerning the location of the lead-based paint in their dwelling unit and how to report deteriorating paint to the owner.Note:Property owners may review with the tenants the types of activities that can disturb lead-based paint and create lead-based paint hazards. These activities include such things as: open-flame burning, renovation and remodeling activities, and dry scraping or sanding of lead-based paint.Licensure of Lead Training Providers and Accreditation of Training CoursesLead training providers must be licensed to offer accredited lead training courses in the State of Maine. A training course, used by an individual to fulfill certification requirements (including renewals), must be approved by the Department. Individuals are responsible for ensuring that a training course is approved by the Department before taking the course. Instructors cannot self-certify as a lead professional by both instructing and attending the same initial or renewal training course. Licensure of lead training providers.

Wipe samples for settled leaded dust can be collected from floors (both carpeted and uncarpeted), interior and sash/sill contact areas, and other reasonably smooth surfaces. Wherever possible, hard surfaces should be sampled. Wipe media should be sufficiently durable so that it is not easily torn but can be easily digested in the laboratory. Recovery rates of between 80-120% of the true value should be obtained for all media used for wipe sampling. Blank media should contain no more than 2 ug/wipe (the detection limit using Flame Atomic Absorption). Additional standards for wipe sampling can be found by consulting ASTM E1728-16.Wipe sampling materials and supplies.Type of disposable wipe: Any wipe material that meets the following criteria may be used:Contains low background lead levels;Is a single thickness;Is durable and does not tear easily (do not use Whatman filters);Does not contain aloe;Can be digested in the laboratory;Has been shown to yield 80-120% recovery rates from samples spiked with leaded dust (not lead in solution); and Must remain moist during the wipe sampling process (wipes containing alcohol may be used as long as they do not dry out).Note: Do not use any other brand of wipes before recovery data has been established. Do not use wipes that contain aloe. Non-powdered disposable gloves. Disposable gloves are required to prevent cross-sample contamination from hands.(3)Non-sterilized polyethylene centrifuge tubes (50 ml size) or equivalent hard-shell container that can be rinsed quantitatively in the laboratory.(3)Dust sample collection forms.(4)Camera to document exact locations (Optional).(5)Template Options. Masking tape; Hard, smooth, reusable templates may be used to define the area to be wiped. Decontaminant templates after each use or; Disposable templates are also permitted so long as they are not used for more than a single surface. Templates must be larger than 0.1 ft2, but smaller than 2 ft2. Templates for floors are typically 1 ft2. Templates are usually not used for windows due to the variability in size and shape (use masking tape instead).Note:Masking tape may damage the painted surface.(6)Container labels or permanent marker.(7)Trash bag or other receptacle (do not use pockets or trash containers at the residence).(8)Rack, bag, or box to carry tubes (optional).(9)Measuring tape.Disposable shoe coverings (optional).Single surface wipe sampling procedureOutline wipe area: Floors: Identify the sample area to be wiped. Do not walk on or touch the surface area to be sampled. If applying masking tape, create about one square foot sample area. No measurement is required at this time. The tape should be positioned in a straight line and corners should be nominally perpendicular. When putting down any template, do not touch the interior wipe area. Windowsills and other rectangular surfaces: Identify the area to be wiped. Do not touch the wipe area. Apply two strips of masking tape across the sill to define a wipe area at least 0.1 square foot in size (approx. 4 inches x 4 inches).Preliminary inspection of the disposable wipes. Inspect the wipes to determine if they are moist. If they have dried out, do not use them. When using a container that dispenses wipes through a “pop-up” lid, the first wipe in the dispenser at the beginning of the day should be thrown away. The first wipe may be contaminated by the lid and is likely to have dried to some extent. Rotate the container prior to each use to ensure liquid inside the container contacts the wipes.Gloves. Don a disposable glove on one hand; use a new glove for each sample collected. If two hands are necessary to handle the sample, use new gloves, one for each hand. It is not necessary to wipe the gloved hand before sampling. Collection of samplesPlace the wipe at one corner of the surface to be wiped with wipe fully opened and flat on the surface. For square sample areas, complete a first wipe pass side-to-side as follows. With the fingers together, grasp the wipe between the thumb and the palm. Press down firmly, but not excessively with both the palm and fingers. Do not use only the fingertips or the heel of the hand to hold down the wipe, because there will not be complete contact with the surface and some dust may be missed. Do not touch the surface with the thumb. Proceed to wipe side-to-side with as many “S”-like motions as are necessary to completely cover the entire wipe area. Exerting excessive pressure on the wipe will cause it to curl. Exerting too little pressure will result in poor collection of dust. Attempt to remove all visible dust from the wipe area.Next, fold the wipe in half with the contaminated side facing inward. The wipe can be straightened out by laying it on the wipe area, contaminated side up, and folding it over. Once folded, place in the top corner of the wipe area and press down firmly with the palm and fingers. Complete a second wipe pass moving from top-to-bottom and wiping the area with “S”-like motions. Attempt to remove all visible dust. Do not touch the contaminated side of the wipe with the hand or fingers. Do not shake the wipe in an attempt to straighten it out, since dust may be lost during shaking.For rectangular sample areas two side-to-side passes must be made over half of this surface, the second pass with the wipe folded so that the contaminated side faces inward. For a windowsill, do not attempt to wipe the irregular edges presented by the contour of the window channel. Avoid touching other portions of the window with the wipe. If there are paint chips or gross debris in the windowsill, attempt to include as much of it as possible on the wipe. If all the material cannot be picked up with one wipe, field personnel may use a second wipe at their discretion and insert it in the same container. Consult with the analytical laboratory to determine if they can perform analysis of two wipes as a single sample. When performing single-surface sampling, do not use more than two single surface wipes for each container. If heavily dust-laden, a smaller area should be wiped. It is not necessary to wipe the entire window well but do not wipe less than 0.10 ft2 (approx. 4” x 4”).Packaging the wipe. After wiping, fold the wipe with the contaminated side facing inward again, and insert aseptically (without touching anything else) into the centrifuge tube or other hard-shelled container. If gross debris is present, such as paint chips in a window well, make every attempt to include as much of the debris as possible in the wipe.Seal the tube and label with the appropriate identifier. Record the laboratory submittal sample number on the field sampling form.Area measurement. After sampling, measure the surface area wiped to the nearest eighth of an inch using a tape measure or a ruler. The size of the area wiped must be at least 0.10 ft2 in order to obtain an adequate limit for lab analysis. No more than 2 square feet should be wiped with the same wipe or else the wipe may fall apart. Record specific measurements for each area wiped on the field sampling form.Form completion. Fill out the appropriate field sampling forms completely. Collect and maintain any field notes regarding type of wipe used, lot number, collection protocol, etc.Trash disposal. After sampling, remove the masking tape and throw it away in a trash bag. Remove the glove; put all contaminated gloves and sampling debris used for the sampling period into a trash bag. Remove the trash bag when leaving the dwelling unit. Do not throw away gloves or wipes inside the dwelling unit where they could be accessible to young children, resulting in a suffocation hazard.Repeat steps 1 through 8 for additional samples in the same dwelling unit.See “Residential Sampling for Lead: Protocols for Leaded Dust and Soil Sampling” from EPA and ASTM E1792-03 (2016) “Standard Specification for Wipe Sampling Materials for Lead in Surface Dust” for further posite wipe sampling. Composite sampling is only allowed as part of a lead hazard screening. Consult with the analytical laboratory to determine if the laboratory can analyze composite samples. When conducting composite wipe sampling, the procedure stated above for single wipe sampling should be used with the following modifications: When outlining the wipe areas (step 1), set up all of the areas to be wiped before sampling. The size of these areas should be roughly equivalent, so that one room is not over-sampled. After preparing the centrifuge tube, put on the glove(s) and complete the wiping procedures for all subsamples (steps 4-5). A separate wipe must be used for each area sampled. After wiping each area, carefully insert the wipe sample into the same centrifuge tube (no more than 4 wipes per tube). Once all subsamples are in the tube, label the tube. Record a separate measurement for each area that is subsampled on the field collection form. Finally, complete trash disposal, making sure that no masking tape is left behind. Risk assessors, inspectors, and sampling technicians do not have to remove their gloves between subsample wipes for the same composite sample if their gloved hands do not touch an area outside of the wipe areas. If a glove is contaminated, the glove should be immediately replaced with a clean glove.In addition to these procedural modifications, the following rules for compositing should be observed:Separate composite samples are required from carpeted and hard surfaces (e.g., a single composite sample should not be collected from both carpeted and bare floors).Separate composite samples are required from each different component sampled (e.g., a composite sample should not be collected from both floors and windowsills).Separate composite samples are required for each dwelling unit.Blank preparation. After sampling the final dwelling unit of the day, but before decontamination, field blank samples should be obtained. Analysis of the field blank samples determines if the sample media is contaminated. Each field blank should be labeled with a unique identifier similar to the others but that identifies the sample as a field blank.Blank wipes are collected by removing a wipe from the container with a new glove, shaking the wipe open, refolding as it occurs during the actual sampling procedure, and then inserting it into the centrifuge tube without touching any surface or other object. One blank wipe is collected for each dwelling unit sampled or, if more than one dwelling unit is sampled per day, one blank for every 50 field samples, whichever is less. Also, collect one blank for every lot used. Record the lot number.Lead inspector decontamination. After sampling, wash hands thoroughly with plenty of soap and water. A bathroom in the dwelling unit may be used for this purpose, with the owner’s or resident’s permission. If there is not running water in the dwelling unit, use wet wipes to clean the hands. During sampling, lead inspectors and risk assessors must not eat, drink, smoke, or otherwise cause hand to mouth contact.Paint chip sampling. Dust sampling must always be done before paint chip sampling in order to minimize the prospect of cross-sample contamination. Paint chip sampling is a destructive method that may release a small quantity of lead dust. Although paint chip samples are to be collected from inconspicuous areas, the occupant must always be notified that paint chip sampling may be necessary.Paint chip sampling tools and materialsSharp stainless steel paint scraper.Disposable wipes for cleaning paint scraper.Non-sterilized non-powdered disposable gloves.Hard-shelled containers (such as non-sterilized 50-mil polypropylene centrifuge tubes) that can be rinsed quantitatively for paint chip samples if results are to be reported in mg/cm2. Sealed baggies can be used only if results are to be reported in ug/g or percent by weight.Collection device (clean creased piece of paper or cleanable tray).Field sampling and laboratory submittal forms.Tape measure or ruler (if results are reported in mg/cm2).Ladder.Plastic trash bags.Flashlight.Masking tape.Heat Gun or other heat source operating below 1,100°F to soften the paint before removal.ContainmentMethod one: Plastic Sheeting Underneath Sampling Area. A clean sheet of plastic measuring four feet by four feet should be placed under the area to be sampled to capture any paint chips that are not captured by the collection device or creased piece of paper. Any visible paint chips falling to the plastic should be included in the sample. Dispose of the plastic after each sample is collected by placing the sheeting in a trash bag. Do not throw away the plastic at the dwelling unit. Wet wipes may be used to clean the area.Method two: “Glovebag” Approach. If further containment is deemed necessary, a “glovebag” approach may be used. A durable sheet of plastic is loosely taped to the surface to be sampled, with a paint scraper, collection device, and shipment container housed inside the plastic. There should be enough “play” in the plastic to permit a scraping motion without dislodging the tape holding the plastic to the surface. Large plastic baggies can be used in lieu of the sheet of plastic if paint chips are to be shipped to the lab in plastic baggies. Properly conducted, this method completely seals the surface during the actual scraping operation. A four by four-foot sheet of plastic is still required under the glove bag to capture any debris that falls to the ground during the glove bag removal. The tape should be slowly removed from the surface to avoid lifting any additional paint from the surface.Paint sample collection. The paint chip sample need not be more than 2-4 square inches in size (consult with the laboratory for the optional size). Persons collecting paint chips should wear new disposable gloves for each sample.The most common paint sampling method is to scrape paint directly off the substrate. The goal is to remove all layers of paint equally, but none of the substrate. A heat gun should be used to soften the paint before removal to reduce the chances of including substrate with the sample and to help prevent sample loss. Including substrate in the sample will dilute the lead content if results are reported in ug/g or weight percent. Hold the heat gun no closer than six inches from the surface. Do not scorch the paint. Discontinue heating as soon as softening or blistering is observed.Use a razor-sharp scraper to remove paint from the substrate. Paint samples collected in this fashion are usually reported in ug/g or % lead only. The sample may be placed in a baggie for shipment to the laboratory.If the area sampled is measured exactly (+/- 1/16th of an inch or 1 mm), and all the paint within that area can be removed and collected, it is possible to also report the results in mg/cm2. All of the sample must be placed in a hard-shelled container for shipment to the laboratory. The hard-shelled container is used since the laboratory will analyze the entire sample submitted. The exact dimensions of the areas sampled must be recorded on the filed sampling form. For mg/cm2, including a small amount of substrate in the sample is permitted.Cleanup and repairAll settled dust generated must be cleaned up using wet wipes.The surface can be resealed with new paint if necessary. If desired, apply spackling and/or new paint to repair the area where paint was removed.Personnel conducting paint sampling should avoid hand-to-mouth contact (specifically, smoking, eating, drinking, and applying cosmetics) and should wash their hands with running water immediately after sampling. The lead inspector should ask to use the resident’s bathroom for this purpose. Wet wipes may be used if no running water is available or if the bathroom is not available.Laboratory submittal. The samples should be submitted to a laboratory accredited by the EPA National Lead Laboratory Accreditation Program. Appropriate sample submittal forms should be used. The field sample number should appear on the field sampling form, the laboratory submittal form, and the container label. The name of the laboratory, the date the samples were sent to the lab, and all personnel handling the sample from the time of collection to the time of arrival at the laboratory should be recorded on a chain of custody form, if appropriate.Other information. See ASTM E1792-03 (2016) and ASTM E1645-16 for additional information.Soil Sampling ProtocolCollection technique general descriptionBare soil samples are typically collected with a coring device or a scooping technique. The device may be used in either of two ways. Most coring devices come equipped with a “T” handle which can be attached to the top of the coring tool or probe. This allows the sample collector to push the tool into the ground. The coring tool can be twisted with the “T” handle as it is pushed into the ground in order to allow the cutting edge of the soil probe to cut through roots and packed earth. In softer soils, a disposable new plastic syringe at least ? inch diameter can be used for each composite sample.The other method for using the coring tool is to attach a hammer device to the top of the coring tool. To utilize the coring tool in this manner, the hammer device is first attached to the top of the coring tool and the tip of the probe is placed on the ground where the sample is to be collected. The hammer is then raised and allowed to fall while it is guided by the sample collector’s hands. The hammer attachment may be the most appropriate tool when the nature of the soils is hard and compacted. Otherwise the “T” handle is easier to use.The soil samples are collected by driving or pushing the coring tool into the ground. The tool is then moved gently from side to side to loosen a plug of soil. The tool is then pulled from the ground and the soil sample is pushed so that the upper part of the soil plug lies between one-inch marks made on the coring device. The top one-half inch of the soil sample is then cut from the core with a stainless steel knife or cutting tool provided for that purpose. This top one-half inch section of the soil core is then transferred to a sample container. All sub-samples are collected in this manner. The collection of sub samples from the sampling line is referred to as a “composite” sample.After collecting a composite sample, the soil probe should be decontaminated or discarded if disposable core liners are used. This process consists of wiping the end of the probe with wet wipes until no more visible dirt is removed from the probe. Similar cores are then collected from the bottom inch of the four-inch core.Materials and suppliesCore sampling devices: Standard soil coring device. Other similar core sampling devices may be used, such as disposable plastic syringes with the end cut off. The plunger is used to remove the soil from the syringe body.Disposable wipes.Non-sterilized 5” x 8” plastic sealed baggies: Unless baggies are 4 mil industrial strength, samples must be double bagged.Non-sterilized non-powdered disposable gloves.Floor plan & property sketch.Soil sample collection form.Laboratory submittal form.Pre-printed labels or permanent ink pen.Trash bag or other receptacle. Do not use pockets or trash containers at the residence.Bare soil sampling proceduresSoil sampling is not recommended when the ground is frozen.The location of soil samples should be recorded on the exterior site plan sketch.Perimeter Sampling Locations: One composite soil sample should be collected so that at least 5 and no more than 10 different aliquots of surface soil are collected from the building perimeter. The aliquots should be collected from all sides of the building where bare soil is present. Each spot should be at least 2 feet distant from each other and 2 feet away from the foundation unless the bare soil is closer than 2 feet.Play Area Sampling Locations: A second composite sample should consist of at least 3 and not more than 10 aliquots collected along an X-shaped grid in the child’s principal play area. Each spot should be at least 1 foot distant from each other. The soil where the aliquots are collected must be bare.The core sampling device should be used to deliver the top ? inch of soil from each spot to the baggie. If paint chips are present, they should not be avoided and should be included in the sample. When sampling play areas, the lead inspector should make an effort to avoid including grass, twigs, stones, and other gross debris in the sample.When all aliquots of the composite sample have been placed in the baggie, the baggie should be zip locked or sealed. If the baggie is not 4-mil industrial weight, the sample should be double bagged. A label with the sample number should be affixed to the baggie. The number should be recorded on the soil platform showing the approximate location of each sample and the soil collection field data form.The core sampler should be cleaned with disposable wipes after each composite sample is collected. If a disposable core sampler is used, it can be used for all sub-samples, but not new composite samples unless it is cleaned thoroughly.Laboratory submittal. Submittal Form Preparation. The sample numbers on the sample container must be the same as those on the field sampling form and must also be used on the laboratory submittal form. Confirm that all samples recorded on are in fact present on the laboratory submittal form. Chain of custody requirements should be followed if applicable.Laboratory analytical procedure. Laboratories analyzing soil samples must participate in the Environmental Lead Laboratory Proficiency Testing Program or equivalent and be an EPA-NLLAP Accredited Laboratory.Additional information.

A fourth composite sample is needed if wall-to-wall carpets are present. The composite samples should be collected from floor, interior windowsills, and window troughs.Risk assessors should follow the composite sampling protocol found in Appendix A of this Chapter. The following rules should be observed when conducting composite dust wipe sampling.Separate composite samples are required from carpeted and hard surfaces (e.g., single composite sample should not be collected from both carpeted and bare floors).Separate composite samples are required from each different component sampled (e.g., a single composite sample should not be collected from both floors and interior windowsills).Separate composite samples are required for each dwelling unit. Floor surface areas sampled in each room should be approximately the same size (1 ft2 or 929 cm2). Window trough and interior windowsill sampling sizes are dependent on window characteristics but should be as similar as possible from room to room (e.g., the surface sampling area should not be skewed so that one room is oversampled).A new wipe should always be used for each spot sampled.No more than four different wipes should be inserted into a single container for a composite sample. Acceptable recovery rates (80-130 percent of the "true" value) have been found when no more than four wipes are analyzed as a single sample (Jacobs, 1993?).While a risk assessor should exercise professional judgement about the number and location of samples, three or four composite dust samples are sufficient for most evaluations in smaller dwelling units.In an unoccupied dwelling unit or a dwelling unit facing turnover, the areas that are most likely to have lead-contaminated dust should be sampled. In general, floor samples should be collected in the four rooms with the greatest evidence of chipping and peeling paint. In a dwelling unit where children reside, however, areas where young children are most likely to be exposed to lead hazards should be sampled. The recommended subsampling locations for houses with children are the following:Principal playroom for children (usually the TV room, living room, or dining room).Kitchen.Bedroom of the youngest child, who is over 6 months of age (children under 6 months are unlikely to be exposed to dust).Bedroom of the next oldest child.The preceding locations for subsamples can be used for both single-family and multifamily dwelling unit risk assessments. However, substitute locations will be necessary in dwelling units where the room designations cannot be determined. For example, in vacant units, the living room should be substituted for the playroom and the smallest bedroom for the youngest child's room.Appendix D: Lead-Based Paint Inspection ProtocolIntroductionXRF performance characteristic sheets and manufacturer’s instructions. When an XRF instrument is used for testing paint in residential dwellings and pre-1978 child occupied facilities, it must have a HUD -issued XRF Performance Characteristic Sheet (PCS). XRFs must be used in accordance with the manufacturer’s instructions and the PCS. The PCS contains information about XRF readings taken on specific substrates, calibration check tolerances, interpretation of XRF readings, and other aspects of the model’s performance.If discrepancies exist among the PCS, the most stringent guidelines should be followed. For example, if the PCS has a lower (more stringent) calibration check tolerance than the manufacturer’s instructions, the PCS should be followed.Inspections in Single-Family Housing. List all testing combinations or each individual surface or component including those that are painted, stained, shellacked, varnished, coated, or wallpaper which covers painted surfaces.Select testing combinationsPerform XRF testing (including the calibration check readings).Collect and analyze paint-chip samples for testing combinations that cannot be tested with XRF, that have inconclusive XRF results, or for client-approved confirmation of XRF results.Classify XRF and paint-chip results.Evaluate the work and results to ensure the quality of the paint inspection.Document all findings in a report at a minimum meeting the requirements of Section 7(A)(3).Listing testing combinations. Develop a list of all testing combinations in all interior rooms, on all exterior building surfaces, and on surfaces in other exterior areas, and fences, playground equipment, and garages as applicable. An inventory of a house may be completed either before any testing or on a room-by-room basis during testing.Number of room equivalents to inspect. Test all room equivalents inside and outside the dwelling unit. The final report must include a final determination of the presence or absence of lead-based paint on each testing combination in each room equivalent. For varnished, stained, or similar clear-coated floors, measurements in only one room equivalent are permissible if it appears that the floors in the other room equivalents have the same coating.Some testing combinations have multiple parts. For example, a window testing combination could theoretically be broken down into the interior sill (stool), exterior sill, trough, sash, apron, parting bead, stop bead, casing, and so on. Because it is highly unlikely that all these parts will have different painting histories, usually they should not be considered separate testing combinations unless their professional judgment and field condition dictate otherwise. (Inspectors should regard parts of building components as separate testing combinations if they have evidence that different parts have separate, distinct painting histories). Windows and doors would typically have at least two combinations, interior and exterior.Number of testing combinations to inspect. Inspect each testing combination in each room equivalent, unless similar building component types with identical substrates (such as windows) are all found to contain lead-based paint in the first five interior room equivalents. In that case, testing of that component type in the remaining room equivalents may be discontinued, if and only if the purchaser of the inspection services agrees beforehand to such a discontinuation. The inspector should then conclude that similar building component types in the rest of the dwelling unit also contain lead-based paint. For example, if an inspector finds that baseboards in the first five room equivalents are all positive, the inspector – with the client’s permission – may conclude that all remaining room equivalents in the unit contain positive baseboards. This is sometimes referred to as a “positive stop.”Because it is highly unlikely that testing combinations known (and not just presumed) to have been replaced or added to the building after 1977 will contain lead-based paint, they need not be tested. If the age of the testing combination is in doubt, it should be tested.Building component types. Results of an inspection may be summarized by classifying component types across room equivalents if patterns or trends are supported by the data.Substrates. Several types of XRF instruments do not require “substrate correction,” needed to correct a systematic bias in an XRF instrument resulting from interference from substrate material beneath the paint. However, all substrates across all room equivalents should be grouped into one of the six substrate categories (brick, concrete, drywall, metal, plaster, or wood) shown on the XRF Performance Characteristic Sheet for the instrument being used. Substrate correction procedures, if required, can then be applied for all building component types with the same substrate. For example, the substrate correction procedure for wooden doors and wooden baseboards can use the same substrate correction value.Number and Location of XRF ReadingsNumber of XRF readings for each testing combination. XRF testing is required for at least one location per testing combination, except for interior and exterior walls, where four readings should be taken, one on each wall. Multiple readings on the same testing combination or testing location are, therefore, unnecessary, except for interior and exterior walls.Because of the large surface areas and quantities of paint involved, and the possibility of increased spatial variation, take at least four readings (one reading on each wall) in each room equivalent. (For room equivalents with fewer than four walls, test each wall.) For each set of walls with the same painting history in a room equivalent, test the four largest walls. Classify each wall based on its individual XRF reading. If a room equivalent has more than four walls, calculate the average of the readings, round the result to the same number of decimal places as the XRF instrument displays, and classify the remaining walls with the same painting history as the tested walls, based on this rounded average. When the remaining walls in a room equivalent clearly do not have the same painting history as that of the tested walls, test and classify the remaining walls individually. For exterior walls, select at least four sides and average the readings (rounding the result as described above) to obtain a result for any remaining sides. If there are more than four walls and the results of the tested walls do not follow a classification pattern (for example, one is positive and the other three are negative), test each wall individually.Location of XRF readings. The selection of the test location for a specific testing combination should be representative of the paint over the areas that are most likely to be coated with old paint or other lead-based coatings. Thus, locations where the paint appears to be thickest should be selected. Locations where paint has worn away or been scraped off should not be selected. Areas over pipes, electrical surfaces, nails, and other possible interferences should also be avoided if possible. All layers of paint should be included, and the XRF probe faceplate should be able to lie flat against the surface of the test location.If no acceptable location for XRF testing exists for a given testing combination, a paint-chip sample should be collected and sent to a lead laboratory recognized by NLLAP for analysis of lead in paint. The sample should include all paint layers and should be taken as unobtrusively as possible. Because paint-chip sampling is destructive, a single sample may be collected from a wall and used to characterize the other walls in a room equivalent. For greater reliability, consider collection and analysis of more than one sample.Documentation of XRF Reading Locations. Descriptions of testing combinations must be sufficiently detailed to permit another individual to find them. While it is not necessary to document the exact spot or the exact building component on which the reading was taken, it is necessary to record the exact testing combination measured. Current room uses or colors can change and should not be the only way of identifying them. A numbering system, floor plan, sketch, or other system, is to be used to document which testing combinations were tested.Side identification. Identify perimeter wall sides with letters, numbers, or Roman numerals. For example, Side A for single-family housing is the street side for the address. Side A in multi-family housing is the apartment entry door side. Side B, C, and D are identified clockwise from Side A as one faces the dwelling unit; thus, Wall B is to the left, Wall C is across from Side A, and Side D is to the right of Side A. Each room equivalent’s side identification follows the scheme for the whole housing unit. Because a room can have two or more entries, sides should not be allocated based on the entry point. For example, giving a closet a side allocation based on how the room is entered would make it difficult for another person to make an easy identification, especially if the room had two closets and two entryways.Room equivalent identification. Room equivalents should be identified by both a number and a use pattern (for example, Room 5-Kitchen). Room 1 can always be the first room, at the A-D junction at the entryway, or it can be the exterior. Rooms are consecutively numbered clockwise. If multiple closets exist, they are given the side allocation: for example, Room 3, Side C Closet. The exterior is always assigned a separate room equivalent identifier.Sides in a room. Sides in an interior room equivalent follow the overall housing unit side allocation. Therefore, when standing in any four-sided room facing Side C, the room’s Side A will always be to the rear, Side B will be to the left, and Side D will be to the right.Building component identification. Individual building components are first identified by their room number and side allocation (for example, the radiator in Room 1, Side B is easily identified). If multiple similar component types are in a room (for example, three windows), they are differentiated from each other by side allocation. If multiple components are on the same wall side, they are differentiated by being numbered left to right when facing the components. For example, three windows on Wall D are identified as windows D1, D2, and D3, left to right. If window D3 has the only old original sash, it is considered a separate testing combination from the other two windows. Codes or abbreviations for building components and/or locations may be used in order to shorten the time needed for data entry. If codes or abbreviations are used, the inspection records and the inspection report must include a table showing their meaning.A sketch of the dwelling unit’s floor plan is required by this protocol. Whatever documentation is used, a description of the room equivalent and testing combination identification system must be included in the final inspection report.XRF Calibration Check Readings. In addition to the manufacturer’s recommended warm up and quality control procedures, the XRF operator should take the quality control readings recommended below, unless these are less stringent than the manufacturer’s instructions. Quality control for XRF instruments involves readings to check calibration. Most XRFs cannot be calibrated on-site; actual calibration can only be accomplished in the factory.Frequency and number of calibration checks. For each XRF instrument, two sets of XRF calibration check readings are required at least every 4 hours. The first is a set of three nominal-time XRF calibration check readings to be taken before the inspection begins. The second occurs either after the day’s inspection work has been completed, or at least every 4 hours, whichever occurs first. To reduce the amount of data that would be lost if the instrument were to go out of calibration between checks, and/or if the manufacturer requires more frequent calibration checks, the calibration check can be repeated more frequently than every 4 hours. If the XRF manufacturer recommends more frequent calibration checks, the manufacturer’s instructions should be followed. Calibration should also be checked before the XRF is turned off (for example, to replace a battery or before a lunch break) and after it is turned on again. For example, if an inspection of a large house took 6 hours, there would be three calibration checks: one at the beginning of the inspection, another after 4 hours, and a third at the end of the inspection.If the XRF is not turned off as the inspector travels from one dwelling unit to the next, calibration checks do not need to be done after each dwelling unit is completed. For example, in multi-family housing, calibration checks do not need to be done after each dwelling unit is inspected, once every 4 hours is usually adequate. Some inspectors do a calibration check between units for two reasons: first, if the instrument goes out of calibration during the inspection of the unit, only that unit needs to be inspected, and, second, if the inspector inadvertently misses a calibration check, the period between checks is less likely to exceed 4 hours.Some instruments automatically enter a “sleep” or “off” state when not being used continually to prolong battery life. It is not necessary to perform a calibration check before and after each “sleep” state episode unless the manufacturer recommends otherwise.Calibration check standard materials. Portable XRF calibration check readings are taken on the National Institute of Standards and Technology (NIST) Standard Reference Material (SRM) or NIST Certified Reference Material using the nominal 1.0 mg/cm2 paint film (or nearly 1.0 in older sets) within the SRM. The complete set of paint films can be obtained by calling (301) 975-2200 or using the NIST SRM site at: checks should be taken through the SRM paint film with the film positioned at least 1 foot (0.3 meters) away from any potential source of lead. The NIST SRM film should not be placed on a toolbox, suitcase, or surface coated with paint, shellac, or any other coating to take calibration check readings. Rather, the NIST SRM film should be attached to a solid (not plywood) wooden board or another non-metal rigid substrate such as drywall or attached directly to the XRF probe. The SRM should be positioned so that readings of it are taken when it is more than 1 foot (0.3 meters) away from a potential source of error. For example, the NIST SRM film can be placed on top of a 1 foot (0.3 meters) thick piece of Styrofoam or other lead-free material, as recommended by the manufacturer before taking readings.Recording and interpreting calibration check readings. Each time calibration check readings are made; three readings should be taken. These readings should be taken using the nominal time which will be used during the inspection, selected from among those specified in the PCS. The open shutter time should be adjusted, if necessary, to reflect the age of the radioactive source. The readings can be recorded on the Calibration Check Test Results form, or stored in the instrument’s memory, and printed out or transferred to a computer later. The average of the three calibration check readings should be calculated, rounded to the same number of decimal places as the XRF instrument displays, and recorded on the form.Large deviations from the NIST SRM value will alert the inspector to problems in the instrument’s performance. If the observed calibration check average is outside of the acceptable calibration check tolerance range specified in the instrument’s PCS, the manufacturer’s instructions should be followed to bring the instrument back into control. A successful calibration check should be obtained before additional XRF testing is conducted. Readings not accompanied by successful calibration checks at the beginning and end of the testing period are unreliable and should be repeated after a successful calibration check has been made. If a backup XRF instrument is used as a replacement, it must successfully pass the initial calibration check test before retesting the affected test locations.Substrate Correction. XRF readings are sometimes subject to systematic biases as a result of interference from substrate material beneath the paint. The magnitude and direction of bias depends on the substrate, the specific XRF instrument being used, and other factors such as temperature and humidity. Results can be biased in either the positive or negative direction and may be quite high.When substrate correction is not required. Some XRF instruments do not need to have their readings corrected for substrate bias on any substrate. Other instruments may only need to apply substrate correction procedures on specific substrates and/or when XRF results are below a specific value. The XRF Performance Characteristic Sheet should be consulted to determine the requirements for a specific instrument and each mode of operation (e.g., nominal time, or time required for intended precision). XRF instruments which do not require correction for any substrate, or require corrections on only a few substrates, have an advantage in that they simplify and shorten the inspection process.Substrate correction procedure. XRF results are corrected for substrate bias by subtracting a correction value determined separately in each house for each type of substrate where lead paint values are in the substrate correction range indicated on the XRF Performance Characteristic Sheet (PCS). In single-family housing, the substrate correction value is determined using the specific instrument(s) used in that house. The correction value (formerly called “Substrate Equivalent Lead” or “SEL”) is an average of six XRF readings, with three taken from each of two test locations that have been scraped visually clean of their paint coating. The locations selected for removal of paint should have an initial XRF reading on the painted surface of less than 2.5 mg/cm2, if possible. If all initial readings on a substrate type are greater than 2.5 mg/cm2, the locations with the lowest initial reading should be chosen. Because available data indicate that surfaces with XRF readings in excess of about 3.0 mg/cm2 or 4.0 mg/cm2 are almost always coated with lead-based paint, and since bleed-through of lead into the substrate may occur, or pipes and similarly interfering building components may be behind the material being evaluated, locations with such high readings should be avoided for substrate correction.After all, XRF testing has been completed but before the final calibration check test has been conducted, XRF results for each substrate type should be reviewed. If any readings fall within the range for substrate correction for a particular substrate, obtain the substrate correction value.On each selected substrate requiring correction, two different testing combinations must be chosen for paint removal and testing. For example, if the readings are inconclusive for some wooden baseboards, select two baseboards, each from a different room. If some wooden doors also require substrate correction, the inspector should take substrate correction readings on one door and one baseboard. Selecting the precise location of substrate correction should be based on the inspector’s ability to remove paint thoroughly from the substrates, the similarity of the substrates, and their accessibility. The XRF probe faceplate must be able to be placed over the scraped area, which should be completely free of paint or other coatings.The size of the area from which paint is taken depends on the size of the analytical area of the XRF probe faceplate; normally, the area is specified by the manufacturer. To ensure that no paint is included in the bare substrate measurement, the bare area on the substrate should be slightly larger than the analytical area on the XRF probe faceplate.In all, six readings must be taken for each substrate type that requires correction. All six must be averaged together. Take three readings on the first bare substrate area. Record the substrate and XRF readings on the “Substrate Correction Values” form. Repeat this procedure for the second bare substrate area and record the three readings on the same form. Substrate correction values should be determined using the same instrument used to take readings on the painted surfaces. If more than one XRF model was used to take readings, apply the substrate correction values as specified on each instrument’s pute the correction value for each substrate type that requires correction by computing the average of all six readings as shown below and recording the results on the “Substrate Correction Values” form. The formula given below should be used to compute the substrate bias correction value for XRF readings taken on a bare substrate that is not covered with NIST SRM film. A different formula should be used when SRM film must be placed over the bare substrate. The PCS specifies when this correction is necessary and provides the formula for computing the correction value.Negative values. If more than 20 percent of the corrected values are negative, the instrument’s lead paint readings and/or the substrate readings are probably in error. Calibration should be checked, and substrate measurements should be repeated.Discarding readings. If the manufacturer’s instructions call for the deletion of readings at specific times, only readings taken at those specific times should be deleted. Similarly, readings between a successful calibration check and a subsequent unsuccessful calibration check must be discarded. Readings should not be deleted based on any criteria other than what is specified by the manufacturer’s instructions. For example, a manufacturer may instruct operators to discard the first XRF reading after a substrate change. If so, only the first reading should be discarded after a substrate change.Classification of XRF Results. XRF results are classified as positive, negative, or inconclusive. A positive classification indicates that lead is present on the testing combination at or above the standard of 1.0 mg/cm2. A positive XRF result is any value greater than the upper bound of the inconclusive range, or greater than or equal to the threshold, as specified on the applicable XRF Performance Characteristic Sheet (PCS).A negative classification indicates that lead is not present on the testing combination at or above the standard. A negative XRF result is any value less than the lower bound of the inconclusive range, or less than the threshold, specified on the PCS.An inconclusive classification indicates that the XRF cannot determine with reasonable certainty whether lead is present on the testing combination at or above the standard. An inconclusive XRF result is any value falling within the inconclusive range on the PCS (including the boundary values defining the range). In single-family housing, all inconclusive results should be confirmed by analysis by a laboratory recognized by EPA, under NLLAP, for analysis of lead in paint, unless the client wishes to assume that all inconclusive results are positive.Positive, negative, and inconclusive results apply to the actual testing combination and to any repetitions of the testing combination that were not tested in the room equivalents. Positive results also apply to similar component types in room equivalents that were not tested. For example, suppose that one baseboard in a room equivalent is tested, and that the inspector decided that all four baseboards are a single testing combination. The single XRF result applies to all four baseboards in that room equivalent.When an inconclusive range is specified on the PCS, the inconclusive range includes its upper and lower bounds. XRF results are classified as positive if they are greater than the upper boundary of the inconclusive range, negative if they are less than the lower boundary of the inconclusive range, or inconclusive otherwise.Different XRF models have different inconclusive ranges, depending on the specific XRF model and the mode of operation. The inconclusive range may also be substrate specific. In some cases, the upper and lower limits of the inconclusive range are equal; that value is called the threshold. If the reading is less than the threshold, then the reading is considered negative. If the reading is equal to or greater than the threshold, then the reading is considered positive. Use of the inconclusive range and threshold is detailed in the performance characteristic sheet. The categories include substrate-corrected results, if substrate correction is indicated. XRFs with only threshold values listed on the PCS are advantageous in that classifications of results are either positive or negative (no XRF readings are inconclusive). Note that the final inspection report should not list inconclusive readings as a third category in addition to positive and negative. There are two options for addressing inconclusive readings:A paint chip may be sampled and sent to a laboratory recognized by EPA, under NLLAP, for analysis of lead in paint.If the client agrees, all inconclusive readings may be assumed to be positive. It is not permissible to assume any inconclusive reading is negative.Evaluation of the Quality of the InspectionRepeated testing of ten surfaces. Data from HUD’s private housing lead-based paint hazard control program show that it is possible to successfully retest painted surfaces without knowing the exact spot which was tested. Select 10 testing combinations at random from the already compiled list in the “Single-Family Housing LBP Testing Data Sheet” for retesting. If possible, the same XRF instrument used in the original inspection should be used in the retesting. If the XRF instrument used in the original inspection is not available and cannot be returned to the site, use an XRF of the same model for retesting. Use the same procedures to retest the 10 testing combinations. The 10 repeat XRF results are compared with the 10 XRF results previously made on the same testing combinations.The repeat readings and the original readings should not be corrected for substrate bias for the purpose of this comparison. The average of the 10 repeat XRF results should not differ from the 10 original XRF results by more than the retest tolerance limit. The procedure for calculating the retest tolerance limit is specified in the PCS. If the limit is exceeded, the procedure should be repeated using 10 different testing combinations. If the retest tolerance limit is exceeded again, the original inspection is considered deficient.Inspections in Multi-family Housing. For inspection purposes only, multi-family housing is defined as any group of more than four units that are similar in construction from unit to unit.Selection of housing units, common areas, and exterior site areas. The first step in selecting housing units is to identify buildings in the development with a common construction based on written documentation or visual evidence of construction type. Such buildings can be grouped together for sampling purposes. For example, if two buildings in the development were built at the same time by the same builder and appear to be of similar construction, all of the units in the two buildings can be grouped for sampling purposes, as can the common areas, and exterior site areas. Units can have different sizes, floor plans, and number of bedrooms and still be grouped.Number of Units to be Tested in Multi-family Building or DevelopmentsNumber of Similar Units, Similar Common Areas, or Similar Exterior SitesPre-1960 or Unknown-Age Building or Development: Number of Units to Test1960-1977 Building or Development: Number of Units to Test1-10AllAll11-13All1014All1015All1216-17All1318All1419All1520All1621-26201627211728221829231830231931241932251933-34261935271936281937291938-39302040-48312149-50312251322252-53332254342255-56352257-58362259372360-69382370-73382474-75392476-77402478-79412480-88422489-95422596-97432598-994425100-1094525110-1174526118-1194626120-1384726139-1574826158-1594926160-1774927178-1975027198-2185127219-2585227259-2795327280-2995328300-3795428380-4995528500-7765628777-9395728940-100457291005-102258291023-103259291033-103959301500874420001165825001457330001748735002031024000232116The specific units to be tested should be chosen randomly from a list of all units in each building or buildings. (For brevity, just “units” are mentioned in describing the random selection procedure, but the procedure is the same for similar units, similar common areas, and similar exterior sites.) The “Selection of Units” form or a comparable form may be used to aid in the selection process. A complete list of all units in each group should be used and a separate identifying sequential number must be assigned to each unit. For example, if apartment addresses are shown as 1A, 1B, 2A, 2B etc., they must be given a sequence number (1, 2, 3, 4, etc.).Note: Units without identifiers cannot not be selected for inspection and would bias the sampling. The list of units should be complete and verified by consulting building plans or by a physical inspection of the development.Specific units to be tested should be selected randomly.Note: Tables of random numbers are often included in statistics books. Today’s common full-function computer spreadsheet software products have random number generator functions of sufficient quality for use in lead-based paint inspections. In Microsoft Excel the code =RANDBETWEEN (X,Y), where X is the first unit number in the list and Y is the final unit number in the list, will generate a random whole number that can be used to randomly select a unit for sampling. The Rand between function is also available in other software, such as OpenOffice.Inspectors are, therefore, advised to use them to obtain the random numbers, which can then be used to select the specific numbered units.The “Selection of Units” form is completed by filling in as many random numbers as are needed in the appropriate column. Numbers for the third column are obtained by multiplying the total development size by each random number. Numbers for the fourth column are obtained by rounding up from the previous calculation to the next whole number. If the whole number in the fourth column has already been selected, that selection should not be entered again. The notation “DUP” should be entered to show that the selection was a duplicate. This process should continue until the required number of distinct sample numbers has been selected. Common areas and exterior room equivalents should be identified at this time, but they are not considered to be separate units.Listing testing combinations and common areas. The “Multi-family Housing LBP Testing Data Sheet” form or a comparable form should be used to list the testing combinations in each unit, common area and exterior site that was selected for inspection. In multi-family housing, the inventory of testing combinations often will be similar for units that have the same number of bedrooms. The inspector should, however, list testing combinations that are unique to each tested unit. For example, some units may contain built-in cabinets while others do not. The selection of testing combinations should, therefore, be carried out independently in each inspected unit.As in single family housing, take readings on all testing combinations in all room equivalents in each unit selected for testing. However, common areas need to be identified and tested as mon areas. Similar common areas and similar exterior sites must always be tested, but in some cases, they can be sampled in much the same way that dwelling units are. Common areas and building exteriors typically have a similar painting history from one building to the next. In multi-family housing, each common area (such as a building lobby, laundry room, or hallway) can be treated like a dwelling unit. If there are multiple similar common areas, they may be grouped for sampling purposes in exactly the same way as regular dwelling units are. However, dwelling units, common areas and exterior sites cannot all be mixed together in a single group.All testing combinations within each common area or on building exteriors selected for testing must be inspected. This includes playground equipment, benches and miscellaneous testing combinations located throughout the development. The specific common areas and building exteriors to test should be randomly selected, in much the same way as specific units are selected using random numbers.The number of common areas to test should be taken from the above table. In this instance, common areas and building exteriors can be treated in the same way as housing units (although they are not to be confused with true housing units).Classification of XRF Results in Multi-family Housing. The inspector should record each XRF reading for each testing combination on the “Multi-family Housing LBP Testing Data Sheet,” or a comparable form, and indicate whether that testing combination was classified as positive, negative, or inconclusive as described previously for single-family housing.When the inspection is completed in all the selected units and the classification rules have been applied to all XRF results, the HUD “Multi-family Housing: Component Type Report” form or a comparable form should be completed. Building component types groups of like components constructed of the same substrate in the multi-family housing development are aggregated on this form. For example, grouping all interior walls would create an appropriate component type if all walls are plaster. Grouping all doors would not be appropriate; however, if some doors are metal and some are wood. At least 40 testing combinations of a given component type in a multi-family housing development must be tested to obtain the desired level of confidence in the results for that component type. If fewer than 40 testing combinations of a given component type were tested, test additional combinations of that component type. If fewer than 40 components of a given type exist in the units to be tested, test all of the components that do exist.In some cases, additional sampling of the specific component may not be necessary. If no lead at or above the standard is found on that component type, additional measurements should be taken in other units to increase the sample size to 40. However, if all or most of the sampled component types are positive, no further sampling is needed, provided that the building owner agrees with this reduction of testing. For example, if 20 out of 60 doors are tested, and the majority is positive for lead-based paint, all similar doors in the buildings may be presumed positive; only those doors tested and found negative may be treated as negative. Note that the inspector and owner may not presume a component is negative. All required XRF testing and/or laboratory analysis must be completed to conclude that any or all components included in a given component type are negative.The substrate and the component for each component type should be recorded on the HUD “Multi-family Housing: Component Type Report” or comparable form under the heading “Description” (for example, wooden interior doors), as should the total number of testing combinations included in the component type. In addition, for each component type, the aggregated positive, negative, and inconclusive classifications should be recorded as described below. Record the number and percentage of testing combinations classified as:Positive for lead-based paint. This is based upon a positive XRF reading in accordance with the XRF’s Performance Characteristic Sheet;Low Inconclusive for lead-based paint. This is based on having XRF readings less than the midpoint of the XRF’s inconclusive range (if the XRF instrument does not have an inconclusive range (that is, it has a threshold value), this aggregation element should not be provided);High Inconclusive (high) for lead-based paint. This is based on having XRF readings equal to or greater than the midpoint of the XRF’s inconclusive range (if the XRF instrument does not have an inconclusive range (that is, it has a threshold value), this aggregation element should not be provided); andNegative for lead-based paint.Positive: Lead-based paint is present on one or more of the components.Negative: Lead-based paint is not present on the components throughout the development. (Lead may still be present at lower loadings and hazardous leaded dust may be generated during modernization, renovation, repair, remodeling, maintenance, painting or other disturbances of painted surfaces.) The decision that lead-based paint is not present throughout the development is reached if:100 percent of the tested component types are negative, or100 percent of the tested component types are classified as either negative or inconclusive and all of the inconclusive classifications have XRF readings less than the midpoint of the inconclusive range for the XRF in use.Note: that the midpoint of the inconclusive range is not a threshold; it is used only for classifying XRF readings in multi-family housing in conjunction with information about other XRF readings as described here.For cases with greater than or equal to 5% positives and less than 15% positives, as well as no positives but greater than 15% high inconclusive, some confirmatory laboratory testing may be needed to reach a final conclusion, unless the client wishes to assume the validity of the XRF results and that all inconclusive are positive.For each testing combination with an inconclusive XRF reading at or above the midpoint of the inconclusive range, a paint-chip sample should be analyzed by a laboratory recognized by the EPA NLLAP for the analysis of lead in paint.If all the laboratory-analyzed samples are negative, it is not necessary to test inconclusive XRF results below the midpoint of the inconclusive range.If, however, any laboratory results are positive on a component type, all inconclusive equal to or above the midpoint of the inconclusive range should be analyzed, or they should be presumed to be positive.Percentages of positive or inconclusive results are computed by dividing the number in each classification group by the total number of testing combinations of the component type that were tested. For example, if 245 wooden doors in a multi-family housing development were tested and 69 were classified as inconclusive with XRF readings less than the midpoint of the inconclusive range, 28 percent [(69 / 245) x 100 percent = 28.2 percent] should be recorded on the form in the “<1.0 percent” columns under the heading “Inconclusive.”Unsampled Housing Units. If a particular component type in the sampled units is classified as positive, that same component type in the un-sampled units is also classified as positive. For those cases where the number of positive components is small, further analysis may determine if there is a systematic reason for the specific mixture of positive and negative results.Note: For example, suppose that a few porch railings tested negative, but most tested positive. Examination of the sample results in conjunction with the building records showed that the porch railings classified as positive were all original and the railings classified as negative were all recent replacements. The records did not reveal which units had replaced railings, and due to historic preservation requirements, the replacement railings were identical in appearance to the old railings. Thus, all un-sampled original porch railings could be classified as positive, and all un-sampled recently replaced porch railings could be classified as negative if at least 40 of the replaced porch railings had been tested or were determined to have been installed after 1978.Fewer than 5% positive results. Where a small fraction of XRF readings, less than 5% percent, of a particular component type are positive, several choices are available:First, the inspector may confirm the results by laboratory analysis, which is considered definitive when performed; a laboratory lead result of 1.0 mg/cm2 or greater (or 0.5 percent by weight or greater) is considered positive.Second, the inspector may select a second random sample (using un-sampled units only) and test the component type in those units. If less than 2.5% of the combined set of results is positive, the component type may be considered as having lead-based paint in isolated locations, but not having lead-based paint development-wide, with a reasonable degree of confidence. Individual components that are classified positive should be considered as being lead-based painted and managed or abated appropriately.Finally, if the client chooses not to confirm the results by laboratory analysis and not to take a second set of measurements, then the component type should be considered as having lead-based paint development-wide. The inspector may wish to advise the client that the cost of additional XRF testing or laboratory analysis is usually much less than the cost of lead abatement or interim control projects. This is of particular interest in the situation where few results are positive, because there is a significant chance that the paint, development-wide, may not be lead-based.Appendix E: Lead Abatement Project Clearance Summary Form MState of MaineDepartment of Environmental ProtectionLead & Asbestos Hazard Prevention Program17 State House Station, Augusta, ME 04333TEL (207) 287-7688 FAX (207) 287-6220alnotifications.dep@Lead Abatement Project ClearanceSummaryForm MImportant NoticeThis form must be completed and submitted to the Maine Department of Environmental Protection by the Maine certified Lead Inspector/Risk assessor who conducted a clearance examination of a notified lead abatement project in accordance with Maine Lead Management Regulations, 06-096 C.M.R.
